What term describes the likelihood that a particular event will occur?

• A. Probability
• B. Frequency
• C. Chance
• D. Significance

Answer: (A)

The likelihood that a particular event will occur is described by probability. Probability measures how uncertain we are about a specific outcome and is written as a fraction, a decimal, or a percent. For a fair coin, the probability of heads is 1/2 (50%), and for a fair six-sided die, the probability of rolling a 4 is 1/6 (~16.7%). Probability can be thought of as the theoretical chance of something happening in a well-defined situation. Frequency is about how often something actually happens in real data, not the inherent likelihood of a single trial. Chance is a common synonym for probability but is less precise in formal contexts. Significance deals with whether observed results are unlikely under a null model, not the basic likelihood of a single event.
